Exemplarily, the blocking member 130 can be inserted between the disk body 110 and the partitioning member 120, or can be clamped and placed between the disk body 110 and the partitioning member 120. After the blocking member 130 is removed, the blocking of the end of the stirring tank 131 close to the reflux channel 121 is released, and the stirring tank 131 and the second tank body 113 can be communicated through the reflux channel 121. In this way, after the painting is completed, only by removing the blocking member 130, the paint in the stirring tank 131 can flow from the reflux channel 121 to the second tank body 113, and be recovered from the leakage channel 116 at the bottom of the second tank body 113, reducing the amount of paint remaining in the paint tray, reducing the waste of paint, and saving paint.

[0080] The partitioning member 120 and the blocking member 130 occupy the space in the receiving groove 111 corresponding to the volume of the partitioning member 120, reducing the amount of paint that can be accommodated in the receiving groove 111, thereby reducing the paint capacity of the roll coating paint tray 10 and reducing the waste of paint.

[0081] Reference Figure 1 、 Figure 2 and Figure 5 In the roll coating paint tray 10 in the embodiment of the present application, a leakage channel 116 can be provided at the bottom of the disk body 110 (that is, the first bottom wall 1111), and the leakage channel 116 can be located at the bottom of the second tank body 113. The paint in the second tank body 113 can be recovered through the leakage channel 116. The bottom of the leakage channel 116 can be used to communicate with the paint container 310 in the coating equipment to recover the paint flowing down from the leakage channel 116 through the paint container 310, reducing the amount of paint remaining in the paint tray, reducing the waste of paint, and saving paint.

[0082] In the roll coating paint tray 10 of the embodiment of the present application, during the coating process, the stirring tank 131 is filled with paint for the paint lifting roller 210 to pick up paint from the stirring tank 131. The blocking member 130 is detachably disposed between the disk body 110 and the partitioning member 120. After the blocking member 130 is removed, the stirring tank 131 and the second tank body 113 can be communicated through the reflux channel 121. In this way, after the coating is completed, only by removing the blocking member 130, the paint in the stirring tank 131 can flow from the reflux channel 121 to the second tank body 113, and be recovered from the leakage channel 116 at the bottom of the second tank body 113, reducing the amount of paint remaining in the paint tray, reducing the waste of paint, and saving paint.

[0083] Reference Figure 1 、 Figure 4 and Figure 5In some possible implementations of the embodiment of the present application, a notch 134 may be provided at the top of the blocking member 130, and the notch 134 may be provided at the middle or both ends of the blocking member 130. Compared with the blocking member 130 without the notch 134, the blocking member 130 with the notch 134 may reduce the maximum paint height that the stirring tank 131 can accommodate, thereby reducing the paint capacity of the containing tank 111, thereby reducing the waste of paint.

[0084] In some possible implementations of the present application, reference is made to Figure 1 and Figure 6 The guide top wall 128 is used to receive the paint flowing out of the outlet 322 of the paint pump 320 in the coating equipment. Exemplarily, the outlet 322 of the paint pump 320 can face the guide top wall 128.

[0085] refer to Figure 1 , the distance between the guide top wall 128 and the bottom of the tray body 110 (that is, the first bottom wall 1111) gradually decreases from the end close to the second trough body 113 to the end close to the first trough body 112. That is, the height of the guide top wall 128 close to the second trough body 113 is higher than the height of the guide top wall 128 close to the first trough body 112, and the guide top wall 128 extends downwardly from the end close to the second trough body 113 to the end close to the first trough body 112, so that the paint from the outlet 322 of the paint pump 320 can flow into the stirring tank 131 along the inclined guide top wall 128, so that the paint roller 210 can pick up the paint from the stirring tank 131. The paint from the outlet 322 of the paint pump 320 flows into the stirring tank 131 along the inclined guide top wall 128 instead of flowing into the second trough body 113, thereby reducing the waste of paint.

[0086] In some possible implementations of the present application, reference is made to Figure 1 The roller painting tray may include a receiving plate 115. The receiving plate 115 may be connected to at least the top of the side wall (i.e., the first side wall 117) of the tray body 110 opposite to the partition 120, and the receiving plate 115 may also be connected to at least one of the second side wall 118, the third side wall 119, and the fourth side wall 1110. One end of the receiving plate 115 away from the tray body 110 extends upwardly and obliquely away from the partition 120. In this way, during the painting process, the receiving plate 115 can receive the paint dripping from the top thereof, and the inclined receiving plate 115 can make the paint on the receiving plate 115 flow more easily into the stirring tank 131, so as to recycle the paint on the receiving plate 115, reduce the waste of paint, and save paint.

[0087] In some possible implementation manners of the embodiments of the present application, the separator 120 may be a hollow structure. The interior of the separator 120 may have a sealed cavity, and the sealed cavity is separated from the receiving groove 111 by the outer wall of the separator 120, so that the paint in the receiving groove 111 is not easily flowed into the sealed cavity. The separator 120 with a hollow structure can, on the one hand, reduce the weight of the entire roller coating paint tray 10, facilitating the use and transportation of the roller coating paint tray 10; on the other hand, it can reduce the consumption of materials for the separator 120.

[0088] In some possible implementation manners of the embodiments of the present application, referring to Figure 6 , the roller coating paint tray 10 in the embodiments of the present application may further include a return pipe 141. One end of the return pipe 141 may be connected to the bottom of the leakage channel 116, and the other end of the return pipe 141 may be used to extend into the paint container 310 of the coating device to guide the paint in the leakage channel 116 into the paint container 310, reducing the situation of paint splashing.

[0089] In some possible implementation manners of the embodiments of the present application, referring to Figure 6 , the roller coating paint tray 10 in the embodiments of the present application may further include a first filter screen 142. The first filter screen 142 is disposed at one end of the return pipe 141 facing away from the leakage channel 116 to filter the paint flowing from the return pipe 141 into the paint container 310, reducing the flow of impurities and the like from the return pipe 141 into the paint container 310.

[0090] Referring to Figure 6 , the embodiments of the present application further provide a coating device, including the roller coating paint tray 10 in the foregoing embodiments. Among them, the specific structure, working principle, and functions of the roller coating paint tray 10 have been described in detail in the foregoing embodiments and will not be elaborated here.

[0091] In some possible implementation manners of the embodiments of the present application, referring to Figure 6 , the coating device may further include a paint lifting roller 210, a transfer roller 220, a scraping roller 230, and a coating roller 240. The axes of the paint lifting roller 210, the transfer roller 220, the scraping roller 230, and the coating roller 240 are parallel.

[0092] The axis of the paint lifting roller 210 is along the length direction X of the tray body 110. The paint lifting roller 210 is disposed above the tray body 110, and a part of the paint lifting roller 210 is disposed in the stirring tank 131 to pick up paint from the stirring tank 131. The paint lifting roller 210 is spaced from the tank wall of the stirring tank 131 of the roller coating paint tray. On the one hand, a part of the paint lifting roller 210 can roll in the stirring tank 131 to pick up the paint in the stirring tank 131; on the other hand, it can reduce the scraping amount of the paint picked up by the paint lifting roller 210 by the tank wall of the stirring tank 131, improving the paint picking amount of the paint lifting roller 210.

[0093] The transfer roller 220 contacts the top of the paint lifting roller 210 to transfer the paint on the paint lifting roller 210 to the transfer roller 220.

[0094] The coating roller 240 and the doctor blade roller 230 respectively contact both sides of the transfer roller 220.

[0095] The coating roller 240 is used to roll and set on the surface of the aluminum strip or other workpieces to be coated, so as to coat the aluminum strip or other workpieces to be coated.

[0096] The doctor blade roller 230 is located above the partition member 120. The diversion top wall 128 on the partition member 120 can receive the paint dripping from the doctor blade roller 230 and divert the received paint into the mixing tank 131, so as to recycle the paint dripping from the doctor blade roller 230, reducing the waste of paint by the coating equipment.

[0097] In some possible implementation manners of the embodiments of the present application, referring to Figure 6 , the coating equipment may further include a backrest roller 250, and the backrest roller 250 is used for the aluminum strip or other workpieces to be coated to wind around, so as to support and transport the aluminum strip or other workpieces to be coated.

[0098] The coating equipment may further include a paint container 310 and a paint pump 320.

[0099] The paint container 310 is used to hold the paint required during the coating process.

[0100] The paint pump 320 has an inlet 321 and an outlet 322. The inlet 321 is communicated with the paint container 310, and the outlet 322 extends to the top of the partition member 120. When the paint pump 320 is turned on, the inlet 321 of the paint pump 320 sucks the paint from the paint container 310 and makes the paint flow out from the outlet 322 of the paint pump 320 onto the diversion top wall 128 of the partition member 120. The inclined diversion top wall 128 guides the paint thereon into the mixing tank 131, so that the paint lifting roller 210 can pick up the paint from the mixing tank 131.

[0101] In some possible implementation manners of the embodiments of the present application, referring to Figure 6 , a first diversion pipe 411 may be connected to the inlet 321 of the paint pump 320. One end of the first diversion pipe 411 is connected to the inlet 321 of the paint pump 320, and the other end may extend into the paint container 310. When the paint pump 320 works, the paint in the paint container 310 flows through the first diversion pipe 411 to the inlet 321 of the paint pump 320.

[0102] The outlet 322 of the paint pump 320 may be connected with a second diversion pipe 412. One end of the second diversion pipe 412 is connected to the outlet 322 of the paint pump 320, and the other end may extend above the diversion top wall 128 of the blocking member 130. When the paint pump 320 works, the paint from the paint container 310 flows through the inlet 321 of the paint pump 320, the outlet 322 of the paint pump 320, and the second diversion pipe 412 to flow above the diversion top wall 128, so as to supplement the paint for the mixing tank 131.
